#Declaration
#Remarks
Use the XPInstantFeedbackView component to work with DevExpress grid controls in instant feedback mode. The component combines the advantages and features of XPInstantFeedbackSource and XPView.
The XPInstantFeedbackView is a read-only data source. To enable data editing in server mode, use the XPServerCollectionSource with the XPServerCollectionSource.AllowEdit property set to true.
XPInstantFeedbackView ships with the following capabilities:
- Ability to handle large data sources with lower memory usage (does not load an entire persistent object instance).
- Ability to customize SELECT statements to exclude unused data columns.
- Ability to include reference property data (nested properties) in the root query to avoid the 1+N problem.
- Ability to include custom (virtual) properties calculated on the server side (similar to ServerViewProperty).
The following examples demonstrate how to work with XPInstantFeedbackView:
